paradigm-ctf-2022's Issues

[Workaround]Docker image "gcr.io/paradigmxyz/ctf/eth-base" does not exist anymore

Looks like the image gcr.io/paradigmxyz/ctf/eth-base:latest doesn't exist anymore and docker build would fail.

Dockerfile:1
--------------------
   1 | >>> FROM gcr.io/paradigmxyz/ctf/eth-base:latest
   2 |     
   3 |     COPY deploy/ /home/ctf/
--------------------
ERROR: failed to solve: gcr.io/paradigmxyz/ctf/eth-base:latest: gcr.io/paradigmxyz/ctf/eth-base:latest: not found

Workaround is to find a backup image from Docker - anjia0532/paradigmxyz.ctf.eth-base and replace that in Dockerfile.
